All pure gold products from KINNO have obtained certification from Food and Drug Administration (FDA). FDA is recognized as one of the largest food and drug regulatory agencies in the world. As a scientific management agency, the FDA's responsibility is to ensure the safety of food, cosmetics, drugs, biological agents, medical equipment, and radiological products produced or imported in the United States. So you can safely use our pure gold leaf as food and cosmetics. We applied for the certificate on Jun 01, 2018.
